Implementing SDN into computer network lessons

Abstract

This paper describes the issue of introducing SDN to students of computer networks. The most important theoretical knowledge is summarized in the form of key points, students should know about. Practical experience is presented in the area of deployment of SDN in data centers with aim on connecting the existing knowledge from traditional computer networks. This connection is explained on problems of traditional networks in data centers and mitigation of these problems by using SDN. Learned information is then extended by presenting a practical demo application in Mininet environment. The application shows possible usage of SDN for making a data center more power-efficient. This application is put in context by the theory of power consumption of data center devices which can be significantly reduced if SDN are used. Purpose of the application is to motivate students to continue in research of SDN area.
